RADIATOR.

Specification of Letters Patent.

Patented Dec. 21, 1920.

Application filed June 14, 1919. Serial No. 304,330.

I '0 all whom it may concern:

Be it known that I, ALBERT PAIENFUSS, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Radiators, of which the following is a specification.

The object of this invention is to provide a new and improved radiator formed of two plates.

Another object of the invention is to provide means for joining the plates together.

These and other objects of the invention will be illustrated in the drawings, described in the specification and pointed out in the claim at the end thereof.

In the drawings,

Figure 1 is a perspective view of a portion of a radiator made in accordance with my invention, a part of the radiator being broken away on a vertical sectional line.

Fig. 2 is a vertical section partly broken away showing the means for fastening the front and back plates together.

In the drawings, like reference numerals indicate like parts.

In the drawings, reference numeral 1 indicates the radiator having a header 2 at the top thereof and a header 3 at the bottom thereof. These headers are connected by the plates at and 5 between which the water circulates. The rear plate 4: is plain while the front plate is embossed with a series of cups 6, 6, the bottoms of "which rest against the plate 4 and hold the plates apart providing a water circulating space between the two plates. At certaln intervals the two plates are perforated, which perforations occur in the two plates in line with each other.

Through these perforations are inserted eyelets 7, the ends of which are expanded and bent over to form flanges which, together with the eyelets, securely fasten the two plates together. The edges of the plates at the sides are soldered together and at the top and bottom are soldered to the headers on either side of the slit provided therein so that circulation may be main tained from the upper header into the space between the plates where the water is cooled and then into the lower header.

The openings secured by the eyelets permit the air to pass through the plates so that the circulation of both air and water in close contact is thereby secured.

I claim:

A radiator comprising a smooth plate and an indented plate, both of said plates being placed against each other in vertical alinement with the indentations of said second plate resting against said smooth plate in order to separate said plates to form circulating space between them, said indentations being perforated at intervals, eyelets clamped in said perforations for the purpose of holding said plates together and providing air openings through both of said plates.

In testimony whereof I affix my signature.

ALBERT PAPENFUSS.
